first embodiment

[0021]FIGS. 1-4B show a receptacle terminal 1 according to the invention. As shown in FIG. 1, the receptacle terminal 1 comprises a contact section 11 for receiving a mating terminal (not shown) and a crimp section 12 for crimping a wire. At a rear end of the crimp section 12 is a carrier section 13, which is used during a manufacturing process.

[0022]As shown in FIG. 1, the contact section 11 has a substantially rectangular shape. A terminal receiving opening 11a extends through the contact section 11. As shown in FIGS. 2 and 4A, the contact section 11 comprises a contact arm 111, a link arm 112, a first protection member 113, and a second protection member 114. As shown in FIG. 4B, the link arm 112 includes a first edge 1121 that extends along a mating direction of the mating terminal (not shown) and a second edge 1122 formed on a side opposite from the first edge 1121. The first protection member 113 includes a first link arm protection member 1131. The second protection member 11...

second embodiment

[0034]According to the receptacle terminal 2 of the second embodiment, the contact spring can be protected and necessary contact pressure can be ensured between the receptacle terminal 2 and the mating terminal (not shown) while the external size of the receptacle terminal 2 is kept small. Further, the bent section 1143 and the first link arm protection member 1131 can protect the link arm 112 with respect to the mating direction.

[0035]FIGS. 7-8 show a receptacle terminal 3 according to a third embodiment of the invention. Elements of the receptacle terminal 3 that are similar to elements of the receptacle terminal 1 of the first embodiment and the receptacle terminal 2 of the second embodiment will be described using the same reference numerals.

third embodiment

[0036]In the third embodiment, a first bent section 112a, which is a point of support when the link arm 112 moves in an up and down direction with respect to FIG. 8, is formed between a link arm 112 and a first protection member 113. The first bent section 112a has a length A. A base 112b of the link arm 112 has a width C. A second bent section 112c on a second surface 114b side of a second protection member 114 has a length B. The ratio of the dimensions A, B and C is 18:12:7.

[0037]The length A of the first bent section 112a in the third embodiment is longer than the length B of the second bent section 112b, as compared to the receptacle terminal 2 of the second embodiment. Because the dimension of the first bent section 112a is made longer without changing the dimension of the second bent section 112c, the contact pressure between the contact member 111a and the mating terminal (not shown) is made higher than the receptacle terminals 1, 2 of the first and second embodiments withou...

Abstract

A receptacle terminal includes a contact section. The contact section includes a substantially L-shaped contact spring, a first protection member, and a second protection member. The contact spring includes a link arm and a contact arm. The link arm has a first edge and a second edge opposite the first edge. The first edge extends in a mating direction of a mating terminal. The contact arm extends along the first edge and has a tip end portion connected to the first edge. The first protection member has a first link arm protection member opposing the second edge. The second protection member has a second link arm protection member opposing the first edge. The receptacle terminal thereby ensures protection of the contact spring and necessary contact pressure between the receptacle terminal and a mating terminal while having a small external size.

Description

FIELD OF THE INVENTION[0001]The invention relates to a receptacle terminal comprising a contact spring and first and second protection members for protecting the same.BACKGROUND OF THE INVENTION[0002]International Publication No. WO 89 / 05531 teaches a receptacle terminal comprising a substantially rectangular contact section. The contact section is formed from a metal plate to have opposing first and second contact springs that extend at approximate right angles to each other. The first and second contact springs each have an L-shaped cross-section. The first and second contact springs apply pressure to a mating terminal to ensure contact pressure between the receptacle terminal and the mating terminal. The receptacle terminal includes a protection member for protecting the first and second contact springs. The protection member, however, disadvantageously increases the external size of the receptacle terminal.SUMMARY OF THE INVENTION[0003]It is therefore an object of the invention ...
